Hi, 

I am currently using NW 7.3.3.
One of the backups completed with the following errors:

<WARNING>:  warning while saving C:\WINDOWS\system32\spool\PRINTERS\FP01926.SHD 
could not be opened and was not backed up. 

<WARNING>:  File C:\WINDOWS\system32\spool\PRINTERS\FP03354.SHD could not be 
opened and was not backed up. 


Is this a serious prob ?

How can I fix this ?

Thanks
